20009: Layer uses the size renderer with an arrow marker symbol

In this topic

A layer in your map is symbolized with the size renderer and uses an arrow marker symbol. Because of differences in the display engine, there may be some discrepancies in the size of the arrows when viewed in a map service or a basemap layer.

Solutions

Switch to a different type of marker symbol, such
as a character marker. Other types of markers do not exhibit these
differences.

Change the symbology properties of the layer to
not use the size renderer.

More information

This warning message is simply telling you that the size of this symbol may be different in a basemap layer or a map service. This is because the drawing engine used by basemap layers and map services scales the size of this type of symbol differently.
